New projects conduct airdrops during the process of token sales, which is a fairly common guideline. But there they benefit more because they want to engage in a lot of promotion activities and many people who come from airdrop are then encouraged to invest in their project. They power their market by promising to give away just a few tokens to everyone. Besides some bad projects who distribute million tokens only to airdrop participants but most of those tokens are worthless.
The airdrop I received turned into money, even though it was small, I got it for free. Don't underestimate the crypto world, there are many unexpected things. For example, if you get an airdrop that has a small value, it could increase by up to 100x the next day. There are many coin projects that can be significant only for certain things. many miracles beyond your expectations
